VEHICLE'IPROPELLED BY M USGLF POWER" Application meamvember 2s, {1"950,H serial Nu. 498,696. ff Y My invention relates to improvements iny vehicles propelled by muscle power.

AThe objects of my invention are:

l. To provide a bicycle with a sidecar attached thereto in such form as not to interfere with the propulsion of the bicycle by the rider; f

2. To provide -means for attaching a sidecar to a bicycle which will secure it firmly thereto and atthe same time reduce to a minimum the shocks and vvibration transmitted by the sidecar to the bicycle.

I attain these objects by the means illustratedv in the accompanying drawings, iny which,-

Figurey 1 is aplan view of a bicycle withl sidecar attached embodyingmy invention; Figure 2 is a side elevation of the same ;2

Figure 3 is a rear elevation of the same;

`Figure 4 is an enlarged sectional detail on the line 4-4 of Figure 5; I, L

Figure 5 is an enlarged sectional detail on the line 5-5 of Figure 2;

Figure 6 is an enlarged sectional detail on the line 6-6 of Figure 2, but kthis view would also be applicable to a similar sectional view of the clamps, 2l, and adjacent parts.

Similar numerals refer to similar partsl l placed around theframe4 members, 10`,`an`d e secured within the rvclamp, 17. Similar 30 throughout the several views.

M y invention comprises a bicycle, 1, with? `front forli, 2,7and rear forli, 3, constructed inV any of the forms now common to the bicycle trade, as I make no claim to any particular form of bicycle. To this bicycle I attach a sidecar comprising a body, l5, a forkedr supporting frame, 10, an axle, 8, and connecting arms, 11 and 12.

Therame, 10, axle, 8, and arms, 1l and 12,

are preferably formed of seamless tubing such as is commonly used for bicycle frames and the different parts maybe brazed together or e otherwise secured in any suitable manner.

The front end of the frame, 10, is bent laterally tol form a connection with the headof the bicycle. This lconnection comprises clamp members, 13 and 14, with bolts,16, securing them together and a split rubber bushing, 15, which surrounds the head, 4 of the bicycle and 4cushions the connection of the clampvthereto. This rubber bushing, 15, is

split at 1505so as to be readilyassembled upon f the head, 4, ofthel bicycle. The clamp mem` ber, 13, has al shank, 13a, formed integral therewith which extends-into and isprefervably brazed to theflateral yextension ofltlie fnamelo. v e

'The arm, 11, kis ,fp1.ieferably formed A.integral withk the axle, 8,- and-is vclampedto one of the lower k,Sidebars of. thebicycle by a clam ,1211, which isfin all respects/similar to the clamp, rafle, showninFigure e' .A p lThe arm, 12,'hasit`s lower endbrazed to the axle, 8,"and arm, 11,'oILis` otherwise suitably united thereto and its upper end-s provided with ak-clamp, 23, in all respects similar tothe clamp, 'wf-14, whichsecures it tothe adjacent kmember of the rear` fork, 3,-of the bicycle; Theclamps, 23 andv211`,a're provided with jruby ber bushingsof ythe same type as the bushing, 15.

., ',1 'Ihe bodyl ofthe car, 6, is secured tothe frame, 10,'by clamps`,`17, whichrespectively surround themembers of the frame, 10, and arebolted to the body, 5,7, by-bolts,20. vSplit rubber bushings or cushions`,18,fare 'enclosed 75 Within the clamps, 17, to' cushion the body,

5, uponthe -frame, '10;v These cushions, 18, Y

are Vsplit at 19l softhat they maybe easily Vably smaller than the bicycle wheels, thus atfording a low center vof gravity for the side- Vcar and permitting an arrangement which gives more leg room for the rider of the bicycle. l

is first mounted upon the frame, 10, and axle, 8, ,as described, and the clamps, 13-14, 23 21, are then putin place withthe rubber cushions inside of them'andboltedsev i curely together. `The sidecar, 5, is preferav1410 Iii-assembling my conveyance, the body, 5, 9,57-

claim:

1. A combined bicycle and sidecar comprisin a bicycle, a sidecar frame, a su orting w eel ivotally attached to the s1 ecar frame. a ody mounted upon the frame, clamping members united to the sidecar frame adapted to embrace the head and a side member of the bicycle frame, and rubber cushions seated within the clamps and surrounding the bicycle members embraced thereby.

2.

3. A combined bicycle and sidecar comrisin a bicycle, a sidecar frame, a sup ortmg w eel plvotally attached to the si ecar frame, a bod mounted upon the frame, clamping mem ers united to the sidecar frame adapted to embrace the head and a side member ofthe bicycle frame, and rubber cushions seated within the clamps and surrounding the cle members embraced thereby.

4. A combined bicycle and sidecar comprisin `a bicycle, a sidecar frame, a supporting w eel pivotally attached to the sidecar frame, a body mounted upon the frame, clamping members united to the sidecar frame adapted to embrace the head and a plurality of the side members of the bicycle frame, and rubber cushions mounted upon the head and side members of the bicycle and embraced with the clamps.

In testimony whereof he axes his signature. y
